Help creating responsive contact form

I am wanting to include a contact form in my website, and am having trouble finding one that I like. I am using Fast Secure Contact Form, but that then renders the form the only thing on my site which is not responsive. Are there any known contact form plug-ins that work well with Pagelines? Or is it easy to create your own?

I have installed that contact form and it has worked very well. The only issue I am having is that only the message body is responsive and the other fields such as Email, Your name and Subject are not. Do you know how to get around this? I am intergrating into the pagelines framework using the div row/spand classes through the following

I have resolved the issue now. I just had to enter a wrapping CSS class within contact form 7 so that it conformed to the grid system in the pagelines framework. Thanks for all the help. Can't believe I hadn't tried out this form before it is really simple and flexible! Good recommendation.
